An optical photobleaching technique has been used to measure the reorientation of dilute probes in freestanding polystyrene films as thin as 14 nm. Temperature-ramping and isothermal anisotropy measurements reveal the existence of two subsets of probe molecules with different dynamics. While the slow subset shows bulk-like dynamics, the more mobile subset reorients within a few hundred seconds ...
Recently, freestanding lms have attracted much attention because they are highly useful in the fabrication of various nanodevices. Freestanding lms can be used on any substrate without deterioration of their own unique properties. Layerby-layer (LBL) deposition has been used widely in the synthesis of freestanding lms, especially of polymer lms with specic physical and mechanical propertie...
We revisit the quantitative analysis of ultrafast magneto-acoustic experiment in a freestanding nickel thin film by Kim and Bigot [1] applying our recently proposed approach magnetic acoustic eigenmodes decomposition Vernik et al. [2]. show that application modeling to time-resolved reflectivity measurements allows for determination amplitudes lifetimes standing perpendicular phonon resonances ...
Microcantilever deflection and the membrane deflection experiment (MDE) were used to examine the elastic and fracture properties of ultrananocrystalline diamond (UNCD) thin films in relation to their application to microelectromechanical systems (MEMS). Freestanding microcantilevers and membranes were fabricated using standard MEMS fabrication techniques adapted to our UNCD film technology. Ela...
